Answer:

1:6

Step-by-step explanation:

3x/8 = 9y/4

Multiply by 8

3x = 9y/4 *8

3x = 18 y

Divide by 3

x = 18y/3

x = 6y

The ratio is of x to y is

Answer:

The total least sale amount is $5,000,000

Step-by-step explanation:

Given as :

The base salary amount of Carmen = $125,000

The commission percentage on total sale = 4%

The performance bonus amount = $25,000

The total compensation amount last year = $350,000

Let The total sale amount = $x

According to question

Total compensation amount last year = base salary amount + percentage on total sale + performance bonus amount

I.e  $350,000 =  $125,000 + 4% of x + $25,000

Or, $350,000 =  $150,000 + 4% of x

Or, 4% of x =  $350,000 - $150,000

Or, 4% of x =  $200,000

Or,  × x =  $200,000

Or, x =

∴   x = $5,000,000

So, The total sale amount = x = $5,000,000

Hence, The total least sale amount is $5,000,000  Answer

Gnesinka [82]

Answer:

$13.25

Step-by-step explanation:

  1. Change 45% in a decimal which is 0.45.
  2. Multiply 0.45 and 25.
  3. That will give you $11.25.
  4. Change 8% into a decimal which is 0.08.
  5. Multiply 0.08 and 25.
  6. That will give you $2.
  7. Then add $11.25 and $2.
  8. Your final answer is $13.25

70 POINTSS!!!! URGETT PLS HELP!! Vectors t = −5i + 2j, u = −3i + 7j, and v = 8i + 20j are given.
LUCKY_DIMON [66]

The angle between the vectors t and u is 45°. And the vector t and vector w are orthogonal to each other.

<h3>What is a vector?</h3>

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

The vectors are given below.

t = −5i + 2j, u = −3i + 7j, and v = 8i + 20j

Part A: Then the angle between vectors t and u will be

\cos \theta = \dfrac{\overrightarrow{a} \cdot \overrightarrow{b}}{|\overrightarrow{a}| + |\overrightarrow{b}|}

Then we have

cos θ = [(−5i + 2j)(−3i + 7j)] / [√{(-5²) + 2²} + √{(-3)² + 7²}]

cos θ = 1 / √2

      θ = 45°

Part B: c is a scalar

If \rm \overrightarrow{\rm v} = (a, b), then \rm c\overrightarrow{\rm v} = c(ca, cb)

Let c = 2, then we have

\overrightarrow{\rm w} = c\overrightarrow{v}\\\\\overrightarrow{\rm w} = (2*8, 2*20)\\\\\overrightarrow{\rm w} = (16, 40)

Part C: Use the dot product to determine if t and w are parallel or orthogonal.

\overrightarrow{\rm t} \cdot  \overrightarrow{\rm w} = (-5, 2)(16, 40)\\\\ \overrightarrow{\rm t} \cdot  \overrightarrow{\rm w} = -5*16+ 2*40\\\\ \overrightarrow{\rm t} \cdot  \overrightarrow{\rm w} = -80+ 80\\\\ \overrightarrow{\rm t} \cdot  \overrightarrow{\rm w} = 0
